Regarding Backup UPS operation

I have a 500 VA backup UPS for my computer. Whenever I switch ON my UPS it takes around 30 seconds to come to normal (to get Green signal), till then orange light will be emitted. I think UPS is in self-test mode at that time. Is it safe to switch ON my CPU and monitor or at least my CPU before UPS coming to normal state, so that I can save that time in booting my computer.

You are correct about the self test and yes, it is safe to turn on the PC while it is going through it. It is a battery and transfer test going on internally, so you'll be fine. However, I agree with Russ. Why, if you have a UPS, would you shut it off? Leave the UPS on in order to get the protection it offers.
